Food, Water, and Energy Security in the Hindu Kush Himalayan Region: A Nexus Perspective
With limited land resources, inadequate energy supply, and growing water stress, South
Asia faces the challenge of providing enough water and energy to grow enough food for the
burgeoning population. Using secondary data from diverse sources, this paper explores the
food, water, and energy nexus from a regional dimension, emphasizing the role of Hindu
Kush Himalayan (HKH) ecosystem services in sustaining food, water, and energy security
downstream. The analysis reveals that the issues and challenges in the food, water, and
energy sectors are interwoven in many complex ways and cannot be managed effectively
without cross-sectoral integration. The most distinctive feature of the nexus in South Asia is
the high degree of dependency of downstream communities on upstream ecosystem
services for dry-season water for irrigation and hydropower, drinking water, and soil fertility
and nutrients. This finding suggests that along with cross-sectoral integration to improve
the resource-use efficiency and productivity of the three sectors, regional integration
between upstream and downstream areas is critical in food, water, and energy security.
Within the nexus approach in South Asia, equal attention should be paid to management of
HKH ecosystems–especially the watersheds, catchments, and headwaters of river systems–
and to tapping the potential of collaborative gains in water, hydropower, and other
ecosystem services through coordination across HKH countries.

addressing the growing challenges of water, energy
& food security.
10. Nexus Challenges: Food Security
• Food production needs to be doubled in next 25
years
• Per capita agricultural land has been declining
• Rice & wheat- high water & energy demanding
• Increased production needs to come from limited or
shrinking areas of cultivable lands

agriculture, water, industry & other economic
activities
• High dependence on traditional sources, fossil
fuels, imported energy
• Reducing reliance upon fossil fuels & carbon
intensity
16. Nexus Challenge: Climate change
• Climate change is a major concern -
alterations in SA - temperature &
precipitation, melting Himalayan
glaciers, and degradation of natural
resources & environment
• Fresh water availability is projected
to decrease
• Increased frequency of extreme
events, drought, floods, variability
in climate, affecting monsoon
patterns

20. Food, water, Energy: Trade-off &
Synergies
• Competition
– Land - for food, energy, hydropower, ecosystem
– Water – for food, energy
– Energy - for agriculture, water
• Complementarities
– Agriculture contributes to energy-biomass, energy
crops, biofuels.
– Better agricultural practices > conserve watersheds
> water availability in dry season
– Good water management, e.g., irrigation efficiency
> reduce demand for water & energy
– Growing biofuels in unused land > energy
security, food security
21. Food, water, Energy: Trade-off &
Synergies
• Policy linkages
– Agric. Policy > water & energy demand
– Energy policy > energy & water demand
– Water policy > irrigation, agric., energy supply
– Energy prices may divert land for energy crops– affect
food security
• Challenge- minimize trade-offs, maximize
synergies
• Subsidizing energy for irrigation > agric production >
overexploitation of groundwater - threatened long-term
agricultural sustainability.
22. 4. Role of Himalayas in
Food, Water, Energy Security in South
Asia
24. Indo-Gangetic Plain- bread basket of
SA
• World’s largest
irrigated agriculture
in IGBP
• Rice-wheat system
produces the bulk of
the food-grains of
SA
25. Ground water recharge
•Himalayan watersheds are
natural storage of water
•Himalayas influences the
ground water condition of
IGBP - Recharge deep
aquifers
•IGBP is rich in ground water
– replenish by rainfall, snow
& ice melting & seepage
from Himalayan watershed
27. Energy Security
• Himalayas have vital role in
energy security in SA
• Hydropower potential 500 GW
(Vaidya, 2012)
• Himalayas can provide access to
green energy
• Of the total hydropower potential in
India, 79% is in the Himalayan
region
• Micro-hydropower
28. Agriculture & Food Security
• Himalayas play significant role in agriculture &
food security in SA through
– Water supply-groundwater recharge
– Sustaining wetland ecosystems
– Maintaining biological diversity, agro-biodiversity
– Himalayan rivers carry soils & nutrients to downstream
– Himalayan river systems harbour richest fish biodiversity
– Connecting Himalayan headwaters with the sea
– Serve as biological corridors for migration of fish & other
aquatic species
– Supporting biological diversity & livelihoods.
29. Challenges of sustaining HKH
Ecosystems
• Degradation of natural resources-
forest, rangeland, soil, watershed, headwaters of
Himalayan rivers
• Environmental degradation- biodiversity
loss, ecosystem degradation, siltation, silting river
beds, declining ground water recharge, drying up
streams,
• Socio-economic impacts- topsoil loss, declining
productivity, water shortages, livelihoods
insecurity, food insecurity, energy insecurity
30. Conclusions
• Regional interdependencies of the food, water, energy
nexus in the HKH mountain systems & downstream.
• Inter-country coordination & collaboration is critical for long-
term solutions for food, water, and energy security in SA.
• Himalayan ecosystem services are vital to both upstream &
downstream food, water & energy security
• A basin-level approach is required to manage synergies &
trade-offs in food, water, & energy nexus.
• The Himalaya is a regional public good, it is common
interest & shared responsibility to protect the Himalayan
ecosystems
31. Recommendations
• Strengthen inter-sectoral coordination
• Recognize the role of HKH mountain
ecosystems, upstream-downstream interdependencies
• Optimum development & sustainable use of Himalayan
water for water, energy & food security
• Manage headwaters of the Himalayan rivers- Himalayan
watersheds, forests, rangelands & farmlands.
• Provide incentives to local communities for sustainable use
& management of the headwaters
32. Recommendations
• Provide alternative energy sources - to reduce black
carbon emissions
• Develop micro & macro hydropower optimally- identify
potential hydropower areas, demarcate fragile zones .
• Framework for regional cooperation for multiple uses
of water for
irrigation, energy, navigation, fisheries, domestic uses
& for benefit-sharing.
• Promote interdisciplinary research & a nexus
knowledge base to support decision-making in
managing trade-offs & promoting synergies
